APPLICATION: Solar Cooking

DESCRIPTION: There are three basic types of solar cookers:


  • Parabolic Reflector
  • Box Cookers
  • Panel Cookers


Parabolic Reflectors are available in two types trough and dish. The parabolic cooker focuses the light from the Sun at or along a focal axis. Dish cookers focus the sunlight onto one point and cook in a similar way to single hotplates. Whilst trough designs are similar to rotisseries and are best used for cooking long thin food such as sausages.


Box Cookers as the name suggests are simply insulated flat collector plate boxes with a reflector panel. The box results in higher sustained temperatures than would normally be obtained with flat plate collectors used in water heating. The reflector is used to increase the amount of radiation that enters the collector.


Panel cookers consists of a number of flat reflection panels that direct light onto a container to be cooked. To retain the heat, the cooking dish is placed within a plastic bag or under a glass bowl.
